Diodes, Inc.'s days of inventory on hand (DOH) has shown fluctuations over the past eight quarters. In Q4 2023, the DOH was 141.76 days, which was significantly higher compared to the previous quarter Q3 2023 at 115.80 days. This increase may indicate that the company is carrying excess inventory or facing challenges in managing its inventory effectively.

Looking further back, Diodes, Inc. had a relatively high DOH in Q2 2023 at 104.47 days, but it improved slightly in Q1 2023 to 107.53 days. However, these figures were still higher than the average DOH in the prior year, possibly suggesting lingering inventory management issues.

Comparing the most recent quarters to the same periods in the previous year, the DOH in Q4 2023 was higher than Q4 2022 at 112.08 days. While the DOH has fluctuated over the past year, the company should focus on optimizing its inventory levels to ensure efficient operations and reduce carrying costs associated with excess inventory.
